A:With the support of ZQ’s powerful research, we can’t do what others can’t, such as super long, super mega-size display screen and heterogeneous display screen, surrounding display screen etc what are difficult to make. We can work out the solution what belongs to you.

A：We always take easy, simple and convenient solution as our targets and orients to make sure all products should be with uniformity and standard. It makes ZQ’s solution easy to acknowledge and operate. As a result, customers avoid complex and various products’ identification. It makes control method easy and single, especially suited to EU and US customers.
 Remark:  Other manufacturers use a transferring card besides sending card and receiving card. However, this transferring card contains hundreds of types and it is complex to us.

A：ZQ can provide constant current chip, control chip, control system, control software and corresponding solution etc four in one service. You can only find this service from ZQ. The service guarantees that ZQ can solve the problems once they happen. We won’t 

A: ZQ’s new scan controller integrates point to point calibration. It is a great progress comparing with color separation and brightness adjustment to any module launched by ZQ before. Point to point calibration can be used in different batches, lighting with different quality to adjust color temperature and brightness. At the same time, it can also adjust color and temperature brightness of the display with some work period. It can recover the display as a new one and more important is that it can improve the view effect of old display which can meet the requests of uniformity view effect to make a perfect display.

Remark: This function is still in development.

A: In all sorts of defaults which cause display not to work normally, cable connections between scan board and module are most often happened. Actions should be taken to prohibit these unnecessary losses.  
Remark: This function is a charged service right now. Cost depends on service.

A：The higher scan frequency is, the less feeling to view scan frequency is, and the clearer images are. For some indoor display in certain places, requirement is not high, but the live recording or broadcast should be met. Not enough scan frequency of past display results in a vast wastage because it just can be made a static display instead of live broadcasting display. ZQ’s 9705X system chip can add frequency up to 1200HZ under condition of 8 scans control. It can be completely used in live broadcasting as exposal speed of common DV camera or camera is 1000HZ.

A: General speaking, the higher level of gray scale is, the more colorful the display shows, the more elegant picture is, the easier detail shows. However, limited by PC display card process capability, at present, the common LED display mainly uses 8 bit process system that is 256 grade gray scales. It is easier understood that there are 256 kinds of brightness changes from black to white. RGB-3 original colors make up 256×256×256＝16777216  kinds of colors. That is what we often say:16 mega colors, also  means 65536 level gray scales. This composes 65536*65536*65536 kinds of colors and improves color processing capacity, meanwhile enhance the display performance, making vividly nature color better.

A：1、Offline heterogeneous processing is realized via software CFVedio and hardware is unnecessary. The max pixels it can control is up to 65536 points.

2、Online heterogeneous process is realized via heterogeneous processor and heterogeneous processor should be purchased in addition. The max resolution it can control is up to 1024 x 768

A:: 1、Check whether power supply is in good condition 
     2、Check the work status of controller is normal
     3、Check whether the connection between controller and light belt is right
     4、Check whether the type of data distributor is right 
     5、Check the BIN setup file of data distributor is correct
